Abstract (en)

[origin: ES8702943A1] Finely divided coating agents based on (A) oligomers and/or polymers containing OH groups and (B) blocked polyisocyanates and, if required, further conventional additives, in which the component (B) contains at least one acylurethane possessing groups of the formula -CO-NH-CO-XR1 (I), wherein X represents oxygen or nitrogen, and, when X is oxygen, R1 represents alkyl, alkoxyalkyl, hydroxyalkyl, aryl, aralkyl or cycloalkyl, and, when X is nitrogen, the radical XR1 represents the group < IMAGE > (II) wherein R2 is C1-11-alkylene, C1-11-alkenylene, or unsubstituted or alkyl-substituted phenylene having up to 8 carbon atoms in the alkyl radical, and Y and Z together form an oxygen atom, or are identical or different and each denote hydrogen or C1-5-alkyl, the coating agent being present in powder form or in the form of a dispersion. The coating agent is used for coating articles exposed to weather, and as top coats and primers.
